My Empire War Game

Bruce brought several blacksmith apprentices to work, and the slaves pushed a material truck to send hundreds of kilograms of weapon scrap into the blast furnace. The blast furnace was hot, and the temperature of the entire blacksmith shop was at least fifty degrees.

Bruce was shirtless, with only a piece of cloth wrapped around his crotch, and instructed everyone to heat the blast furnace. Since there is no coal, the blacksmith can only use charcoal for heating.

The heat provided by charcoal is limited, only 700 degrees. Of course, this is in an open environment. If it is in a special furnace, the temperature can reach a maximum of 900 to 1,000 degrees, while the temperature required for steel smelting is at least 1,000 degrees. Above, at this time, bellows blowing is needed to support combustion to reach the ironmaking temperature.

Su Lun didn't know much about ironmaking, but he remembered that after heating the air in advance and then injecting it into the ironmaking furnace, the temperature of the furnace could be raised by about 200 degrees, so that the temperature of the ironmaking furnace could reach a thousand taels. Baidu, the temperature is a little higher than that of using coal to make steel.

In fact, although the use of coal for ironmaking has many advantages, such as fast ironmaking, high output, and low cost, it has a serious defect, that is, the sulfur content of coal. Most coals have high sulfur content. Using it to make iron will make the iron also contain sulfur, which will cause a serious consequence, the iron will become brittle.

The quality of iron has declined, and the forged weapons cannot be compared with weapons that do not contain sulfur at all. When they are cut, they will even break directly. This situation cannot be compensated for by the low cost.

After all, no matter how low you spend, the things you buy can't be used, so the money spent is of no value at all.

As for steelmaking, Su Lun also only understands a little bit. The difference between steel and iron lies in the amount of carbon content. If the carbon content is too much, it is iron, and if the carbon content is too low, it is steel. If the carbon content is too low, it is wrought iron. What is the specific proportion among them, Su Lun really does not know.

"If I had known that I would travel through time, I should have written down all these knowledge points." Su Lun rubbed his head and complained.

Although I don't know the specific carbon content of steel and iron, as an experienced blacksmith, Bruce still has some experience. Beat after heating.

This method of repeatedly beating and heating iron ingots is to forge steel. After the iron ingot is repeatedly tempered, it is called a smelting. This operation is repeated a hundred times and it is called a hundred steelmaking. It is also the best steel on the market at present. All kinds of iron and steel weapons are the elite of the elite. In the Kingdom of Florence, the weapons and armors used by most armies are usually made in thirty.

Of course, there are weapons that are better than this kind of steelmaking, that is, the weapons made by dwarves. Of course, although the technology of dwarves is higher than that of humans, it is actually very difficult for dwarves to forge steelmaking, but they have other unique secrets.

After seeing the normal production of the blacksmith shop, Su Lun began to look for ideas to make money. The territory has been investing in but not producing. This is also a lot of pressure for Su Lun. When Johnson left, Su Lun gave him a hundred gold coins. Well, he now has only two hundred gold nars left in his hand.

There are still some things in the storage space, two pieces of fine iron, some gems, and two silver treasure chests. The gems are the rewards obtained by defeating the natives last time, and Su Lun checked them. Most of these gems are of average quality. , only two are of good quality, and they can be sold to gem merchants for up to three or four hundred gold coins. This gold coin is estimated to be spent in a month.

And the distance from the territory to be self-sufficient, it is estimated that it will take at least two years to have income. When he thinks of this, Su Lun wants to rob the treasure of the giant dragon. According to legend, the giant dragon is very rich. Of course, he can only think of this idea. Think, let's not say that giant dragons are rare now, even the power of the giant dragon itself requires at least a legend to fight against it.

"By the way, there are still two treasure chests that have not been opened." After saying that, Su Lun chose to open the treasure chests.

A flash of light flashed, the treasure chest disappeared, and a system prompt sounded in his ears.

"Congratulations to the host, you have obtained a mechanical control."

"Congratulations, host, you got a bottle of Beidou Tianmao."

"Mechanical control? What is this?" Su Lun picked up the book and flipped through it. The book recorded the manufacture, principle and use of various machines. After reading the introduction of the system, Su Lun realized that this is also a new skill generated by the integration of the system skills in this world.

In the original game, this skill was controlled by machine iron, which could summon mechanical soldiers such as wooden cows and horses, but after arriving in this world, it became a crafting machine, and even if you learned it, you couldn't make wooden cows and horses, and you still need to improve it later.

The system is not too pitiful this time, and gives an upgrade route. First, you need to upgrade the mechanical control to the advanced level, and then learn the mechanical iron secret technique. After learning the mechanical iron secret technique, you must find an NPC, and the Peach Blossom Immortal will pass it. After the test, you will get a reward, this reward is awesome, it is actually the craftsmanship of the puppet golem.

This system actually brought out the wizard's golem making process, and directly turned some of the iron men inside into steel golems. The steel golem Su Lun has never seen it, but his reputation is still known. There is no problem with a steel golem sweeping a knight group. Note that it is not a cavalry, but a knight.

Forget the puppet golem, the peach blossom fairy still doesn't know where to find it? In the game, Peach Blossom Immortal can be found as long as you go to Taolin. In reality, where do I go to find him? This broken system does not give a hint.

Although mechanical puppets cannot be made, this mechanical manipulation is still useful, such as making some simple mechanical tools to speed up the construction of territories, and making a hydraulic forging machine and a hydraulic blower for the blacksmith shop.

With a hydraulic forging machine, the speed of forging steel can be increased by at least dozens of times. After all, manual beating is not comparable to a machine, and the machine's beating speed is uniform and the force is sufficient. Originally, he wanted to find some craftsmen for research, but now using this mechanical control, he can make one by himself.

After learning the mechanical control, Su Lun picked up a glass bottle next to him. The bottle contained blue translucent liquid. As the bottle swayed, the liquid inside was flickering with stars, which looked very beautiful. This thing is also rare in the game, its effect is very simple, is to increase the attribute.

[Beidou Tianmao: The magical liquid formed by the power of the stars, which can enhance strength or physique after use. After use, strength or constitution attribute +3, only one type is triggered each time, and it can be used repeatedly. 】
